APPARATUS FOR REMOVlNG COKE FROM OVENS.

QPECIPICATION forming part of Letters. Patent No. 314,510, March 2 2, 1885.

Application filed January 15, 1885.

T0 aZZ whom it may concern.-

Be it known that I, GEORGE W. Brenna, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Removing Coke from Ovens or Kilns; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, in which- Figure 1 is a side elevation; Fig. 2, a front elevation; Figs. 3 and 4., detail sectional views.

This invention has relation to the provision of means and apparatus for theremoval of charcoal or coke from ovens or kilns, and has for its object to provide an apparatus of such a construction as to be capable of removing the coke or charcoal from the ovens or kilns and loading it directly onto the ears or carts without the necessity of any extra hauling and with but little manual labor, the power being supplied bya steam-engine or other suitable motor.

Referring to the accompanying drawings, Fig. 1 is a side elevation of my improved apparatus with boiler and engine attached, the whole being carried by trucks running on tracks laid in suitable position near the ovens or kilns.

The frame is made of cast metal or other suitable material, and consists of two upright side pieces, A A, mounted on a platform and suitably connected together to form the housing.

At the upper edges of the side pieces, A A, on their inner sides, are formed channels a a, in which, by means of tonguesbbon each side thereof, the sliding block B is carried and allowed to be freely and easily moved in a horizontal direction in the channels a a.

To the top of the sliding block 13 is rigidly fastened another block, (lto which is attached, by means of pin 5", which slides in recess 2) on top of block C, the lateral] y-adj ustable block 0. The block 0 has hinged to it, by hinge c, at the rear end thereof, a box,0. Placed with in this box 0 in such a manner as to permit of ahorizontal adjustment are the picks D D D,

(No model.)

said picks being made of rods or bars of metal having one end bent down to form the pick, and having a rack formed on their upper sides at or about the middle of the bar and extendingover a portion or all of the straight arm or handle of the pick.

0n the top of the box 0 is journaled an axle, E, carrying a gear-wheel of such dimensions as to gear with the racks d on the upper sides.

of the picks D D D. The axle E is supplied with a crank or handle, F, suitably attached thereto, and by which the axle E and gearwheel e are operated. It can also be fitted with a ratchet-wheel and dog for holding it in any desired position.

To the rear end of the block B is attached an arm, M, for the purpose of longitudinally reciprocating said block. This arm is connected to the motive power either by being directly geared to the piston or by any other suitable means as, for instance, as shown in the drawings, where it is attached to the balanee-wheel H of the engine.

Near the outer end of the pick-arms D D D is placed a lever, d. This lever is pivoted to the frame and operated by the treadlc or footpiece 01'.

At the forward end of the frame A A is placed a chute, It, elevated at one end and held in position by arms or rods secured to the side pieces, A A, or to the base of the frame. At the lower end of this chute It, and to one side of the frame, is held a pan, J, having a gate in the bottom thereof, said gate being retained in position by means of hinges and a trip-bolt.

At the same sideofthe frame, extending from under the pan J to the rear end of the platform, is placed an endless apron, K, supplied with boxes k. Said belt is held in position and receives motion from drums Z Z,whicll1 in turn are moved by suitable belts or gearing from the engine.

The boxes 7t 7t, &c.,are constructed with arms extending upwardly for the purpose of operating the trip-bolt on the pan J, whereby the bottom gate of the pan 5- is opened and the contents thereof allowed to fall into the boxes as the boxes pass under the pan. \Veights or springs may be used for raising the bottom gate of the pan when the contents are dumped into the boxes. 4

At the opposite end of the truck from the pick-frame is placed a platform or chute, L, the upper end of which is in close proximity to and under the rear drum of the endless apron, and the lower end extending out over the platform on which the apparatus is carried. The operation of the apparatus is as follows: The trucks or cars which carry the apparatus are moved on the track provided for that purpose, bringing the apparatus directly in front of the door of the oven or kiln. The picksD D D are then drawn backward by means of the gear 6 and racks d, to give as short a reach as possible to the picks. The power is then applied to the machine and the picks are moved forward into the door of the kiln or oven. As the rounded or curved parts of the picks strike the coke or charcoal they are raised by means of thelever d, operated by treadle (1, attached to the frame. As the picks move backward they are allowed to drop, and the points thereof take hold on the coke and draw it from the oven and into the chute B, which carries it down to the pan J, and from thence, by means of the apron K, to the cars or carts. As the oven is emptied the picks D D D are regulated by the racks (Z and gears e to enter farther into the oven. They are also moved from side to side as may be desired by the sliding connection between G and O.

The pin on the bottom of block 0 may either be rigidly attached to O or it may form a swivel, so as to permit the block 0 and the picks attached thereto to be completely turned around.

Having described my invention, I claim 1. In a machine for drawing coke from ovens,

the combination, with the main frame A, of 0 the reciprocating block B, supported on said frame,thelaterally-traveling block 0, mounted and moving on the block B, and the longitudinally-reciprocating forks or picks carried upon the block 0, substantially as described.

2. In a machine for drawing coke from ovens, the combination, with the main frame A and horizontally reciprocating block B, having block 0 and box 0 mounted thereon, and carrying the pinion e, of the fork or pick D, arranged within said box 0 and having teeth to engage with said pinion, whereby the fork or pick may be fed forward and backward irrespective of the movement of the block B, substantially as described.

3. In amachine for drawing coke from ovens or kilns, the combination of frame A A, block B, sliding thereon and receiving motion from rod M, and having block 0 and box 0', carrying picks or forks D DD, mounted thereon, with chute R and endless apron K, moving under said chute, as set forth.

4. In a machine for drawing coke from ovens or kilns, the combination of frameAA, block B, sliding thereon, and picks or forks D D D, provided with means. substantially as shown, for giving lateral and horizontal motion to the forks or picks, and lever d and treadle d, for

raising the ends of the picks or forks as they enter the oven or kiln.

In testimony that I claim the foregoing as my own I have hereto ai'fixed my signature in presence of two witnesses.

GEORGE w BIEBER.
